System and method for use of a short beacon in a wireless communication network
First Claim
1. A method of beacon transmission in a wireless communication network, the method comprising:
- generating a short beacon comprising PHY information, wherein the short beacon excludes MAC information;
transmitting the short beacon via the wireless network;
transmitting a conventional beacon request in response to the short beacon; and
transmitting a conventional beacon in response to the conventional beacon request.

Abstract
A system and method for use of a short beacon in a wireless communication network is disclosed. In one embodiment, the method comprises generating a short beacon comprising PHY information, wherein the short beacon excludes MAC information and transmitting the short beacon via the wireless network. In general, three types of short beacons are disclosed, a first type consisting only of a PHY preamble, a second type also including a PHY header, and a third type also including a MAC header. In addition, the scheme of common beacons and individual beacons is described. Common beacons are broadcast omni-directional at the beginning of each superframe with low data rate and individual beacons are unicast to individual devices directionally with high data rate. A common beacon contains information intended for all of the devices of the network. An individual beacon contains information intended for one particular device.
